✏️ Measuring Variability

===========================================

[tex] \large\bold \blue{x : } [/tex]

  • 1.)48 is the midpoint

[tex] \bold{46 + 50 = 96 \div 2 = 48}[/tex]

  • 2.)43 is the midpoint

[tex] \bold{41 + 45 = 86 \div 2 = 43}[/tex]

  • 3.)38 is the midpoint

[tex] \bold{36 + 40 = 76 \div 2 = 38}[/tex]

  • 4.)33 is the midpoint

[tex] \bold{31 + 35 = 66 \div 2 = 33}[/tex]

  • 5.)28 is the midpoint

[tex] \bold{26 + 30 = 56 \div 2 = 28 }[/tex]

  • 6.)23 is the midpoint

[tex] \bold{21 + 25 = 46 \div 2 = 23}[/tex]

✏️Note: To be able to get the answer you should add the scores and divided to 2

[tex] \large \bold \blue{fX : }[/tex]

  • 1.)fX is 48

[tex] \bold{1 \times 48 = 48}[/tex]

  • 2.)fX is 430

[tex] \bold{10 \times 43 = 430}[/tex]

  • 3.)fX is 380

[tex] \bold{10 \times 38 = 380}[/tex]

  • 4.)fX is 528

[tex] \bold{16 \times 33 = 528}[/tex]

  • 5.)fX is 252

[tex] \bold{9 \times 28 = 252}[/tex]

  • 6.)fX is 92

[tex] \bold{4 \times 23 = 92}[/tex]

✏️ Note you have to multiply the mean to f to get the fX
